Application filed June 19.

To all whom it may concern:

Be it known that I, Jorrrr BINGMAN, a citizen of the United States, residing at Mount Tabor, in the county of Vernon, State of Wisconsin, have invented certain new and useful Improvements in Attachments for Hydrocarbon Containers, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in attachments for liquid containers and particularly to attachments for metal containers of oils, gasoline, kerosene, and the like.

The principal object of the present invention is to provide a novel and improved device whereby the loss of the contents of the container, through expansion by heat, is prevented, as well as to prevent fires with the consequent loss of life and property.

Another object is to provide a novel and improved device which is applied to the lower side of the head of the barrel for the purpose of producing an air cushion for the expanding liquid, whereby the walls and ends of the barrel will be protected against leakage.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanylng drawing.

In the drawing:

Figure 1 is a vertical sectional view through the upper portion of a metal barrel showing the invention in elevation.

Figure 2 is a similar sectional 'view but showing the member 12 in section.

Figure 8 is a horizontal sectional view taken on the line 3-3 of Figure 2, looking upwardly.

When oil, gasoline, or the like are placed in the metal barrels now used for this purpose, they are permitted to fill the barrels up to the level of the lower faces of the heads of the barrels. l/Vhen a barrel, so filled, is left standing in the hot sun for any length of time, the heat from the sun causes the liquid to expand, with the result that leakage is caused through the filling and air vent openings, around the closure, permitting the loss of too great a percentage of the contents of the barrel. The present device contemplates the provision of an air chamber within the barrel head and in which air will Specification of Letters Patent.

be trapped when the barrel is filled and the head placed in position, the air chamber being in such position that when the liquid expands the part which would ordinarily escape from the barrel is permitted to eX- pand into the said air chamber, compressing the air, and thus relieving the walls and ends of the barrel from the pressure of the expanding liquid.

Referring particularly to the accompanying drawing, 10 represents the upper portion of a metal barrel which contains a liquid hydrocarbon, and 11 the metal head of the barrel. Secured to the lower face of the head 11, centrally thereof, is a downwardly flaring metal tube, constituting a chamber or pocket, the lower end of which is open, said tube being represented by the character 12. The contents of the pocket is to be approximately about two and one-half percent of the contents of the barrel. The barrel head is formed with the usual filling bung hole 18, in which is placed the closure plug or stopper, and the air vent opening 14, having theelosure plug 15 therein.

When the barrel is filled, the level of the liquid is permitted to rise to the line 16, after which the head is placed in position and secured in the usual manner. When the head is placed in position within the barrel, air will necessarily remain in the pocket 12, and as the tube descends into the upper portion of the liquid this air will be slightly compressed, with the result that only a small portion of the liquid will rise therein. The barrel is now filled through the bung-hole 13, and the hole and the opening 14 closed.

Later when the liquid expands under conditions such as above described, its volume will necessarily be increased, and this excess will enter the pocket and compress the air therein, such air acting as a cushion and preventing the usual pressure against the walls and heads of the barrel. Generally this pressure causes a loosening of the bung stoppers and the leakage of liquid through the bung openings and around the stoppers. lVith the present device, this excessive pressure is permitted to spend itself against the air cushion in the pocket 12, thus protecting the barrel from damage and also preventing loss of a portion of the contents.

What is claimed is: I

The combination with a liquid containing barrel, and the head thereof, of a clownwardly flaring pocket mounted on the lower 7 face of said head and projecting doWnWardcontaining air against which the excess vol- 10 1y, its upperend being'closed and its lower umeofthe liquid presses when such liquid end open for the purpose described. expands Within the receptacle.
